See your PCP. Some conditions like ear discharge, loss of hearing require further assessment and your PCP may schedule a follow-up appointment or refer you to an ENT specialist to determine a diagnosis. See your PCP first for evaluation and tests.
Swimming? Sounds like swimmer's ear - external otitis. See ENT doc for exam/treatment.
